ALVIN TAPLIN AND H. D. BRADLEY, OF FORESTVILLE, ASSIGNORS TO THE-BRISTOL BRASS AND CLOCK COMPANY, OF BRISTOL, CONNECTICUT.

Letters Patent N 94,451, dated August' 31, 1869.

`lh Schedule referred to in than Letters Patent and making putof thesame.

To all whom it may concern:

Beit known that we, ALVIN TAPLIN and H. D. BRADLEY, of Forestville, inthe county of Hartford, and State of Connecticut, have invented a newand useful Improvement in Lamp-Burners, of which the following is afull, clear, and exact description, refer ence being had totheaccompauyng drawing, forming part of this specification, and inwhich- Figure 1 represents a vertical or longitudinal section of alamp-burner, constructed in accordance with our improvement, taken asdenoted by the line x .t in

Figure 2, which latter is a transverse section of said burner, throughthe line y y in iig. 1

Figure 3 is a top view, or plan of the burner.

Y Similar letters of reference indicate corresponding parts.

Our invention relates to lamp-burners, in which two flat wicks are used,and the same converted or bent, as they are fed up through the upperportion of the burner, into,or so as virtually to constitute a singlewick of annular form; and

'.lhe invention consists in a reversed lateral arrangement of thewick-tubes beyond each other for a portionof their length above thebottom of the burner, whereby provision is established fol-'hold on thewicks by the feeder, at or near their one edge; and

The invention further consists in a combination, with such anarrangement or constructionof the tubes in an oblique disposition,relatively to the latter, of a single wick-lifter, fitted with feeders,so arranged as that they bite on the two wicks at or near theiroppoposite edges, and on the bodies or intermediate portions ofthe wick,substantially as hereinafter' described.

Referring to the accompanying drawing- A and B represent the twowick-tubes of the burner C, which may be fitted or provided with ahinged basenozzle, a, to allow of entryof the wicks from'below, and, bymeans of a screw-thread on its lower end, lserving to establishconnection of the burner with the amp. p

These wick-tubes or passages A and B are of a straight or flatconfiguration at their lower ends, and for some distance upward,rradually merging'into a semicircular form on opposite sides of acentral airpassage and guiding-tube, D, having lateral hollowwedge-shaped branches or guides, b b, which serve to admit air fromopenings c, in the sides of the burner, up through the tube D, and inconnection with'the latter, to direct the wicks d and e till they emergefrom the top of the burner in the shapeof asingle annular wick, asin thecase of other two-wicked arrangements applied to an argand-burner.

The wick-tubes or passages A and B, however, in

our improvement, are only in line, as it were, at the upper portion ofthe burner, and gradually set, for the remainder of their length, in a.downward direction to opposite sides at their edges, causing them tooccupyA a reversed lateral arrangement beyond eachother, or

so that they overlap one another, at their edges, on'

opposite sides of the burner, but lying in juxtaposition, side by side,as represented in iig. 2.

An opening, f, is made between these tubes, at their point or place offeed, for a purpose that will he hereinafter described. V

The wick-lifter E we set obliquely, relatively to the wick-tubes, attheir straight or flattened-outportions,

and, so far as its general position is eoncerued, outside of the onetube, and arrange the feeders g g and h thereon,.` so that in turningthe lifter, the two end or outside feeders g g bite directly on thewicks d and e, and their edges or portionswhich li'e in the later'-ally-extended or overlapping parts of the'tubes, while the intermediatefeeder or feeders' h bite or bear on 4the wicks in between suchedge-grip, and in part indirectly, so lfar as regards the lone wick e,by the interposition of the other 'wick d, which is bent by theintermediate feeder or feeders h, to enter the other wick-tube, and bearagainst the adjacent wicke, to accommodate which action and arrangement,is the object of the opening f between the tubes.

, By this construction and arrangement of parts, the two wicks aresteadied and operated on, in a uniform and positive manner, by thesingle lifter, and the burner so fitted may be got up cheap.

What is here claimed, and desired to be secured by` Letters Patent, is-

1. The wick-tubes A and B, constructed and arranged to overlap eachother, at their edges, on opposite sides of the burner, for a portion oftheir length from the bottom of the latter, and shaped or bent above toform an annular wick-course, substantiallyv
